The former U.S. official said that parts of the U.S. government were informed that Zardari had a “minor heart attack” on Monday night and flew to Dubai via air ambulance today. He may have angioplasty on Wednesday and may also resign on account of “ill health.”

“This is the ‘in-house change option’ that has been talked about,” said Shuja Nawaz, director of the South Asia Center at the Atlantic Council, in a Tuesday interview with The Cable. Nawaz said that this plan would see Zardari step aside and be replaced by his own party, preserving the veneer of civilian rule but ultimately acceding to the military’s wishes to get rid of Zardari.

“Unfortunately, it means that the military may have had to use its muscle to effect change yet again,” said Nawaz. “Now if they stay at arm’s length and let the party take care of its business, then things may improve. If not, then this is a silent coup with [Pakistani prime minister Yousaf Raza] Gilani as the front man.”
